# $NetBSD: opt-query.mk,v 1.7 2022/08/18 05:37:05 rillig Exp $

#
|
|
# Tests for the -q command line option.
|
|
#
|
|
# The -q option only looks at the dependencies between the targets.
|
|
# None of the commands in the targets are run, not even those that are
|
|
# prefixed with '+'.
|
|
|
|
# This test consists of several parts:
|
|
#
|
|
# main Delegates to the actual tests.
|
|
#
|
|
# commands Ensures that none of the targets is made.
|
|
#
|
|
# variants Ensures that the up-to-date status is correctly
|
|
# reported in both compat and jobs mode, and for several
|
|
# kinds of make targets.
